    Abstract: The present invention provides a bi-directional microelectromechanical element, a microelectromechanical switch including the bi-directional element, and a method to reduce mechanical creep in the bi-directional element. In one embodiment, the bi-directional microelectromechanical element includes a cold beam having a free end and a first end connected to a cold beam anchor. The cold beam anchor is attached to a substrate. A first beam pair is coupled to the cold beam by a free end tether and is configured to elongate when heated thereby to a greater temperature than a temperature of the cold beam. A second beam pair is located on an opposing side of the cold beam from the first beam pair and is coupled to the first beam pair and the cold beam by the free end tether. The second beam pair is configured to elongate when heated thereby to the greater temperature.

    Abstract: A system and methods for base excitation of moderately high vibration of micro-cantilevers are disclosed. A micro-cantilever may be coupled to one or more actuators adjacent its base. The actuators may comprise bulk materials, bridges, or formed wires that expand and contract by application of electric currents, due to, for example, the effect of electro-thermal heating or piezoelectric effects. Single actuators or an array of actuators may be placed around the micro-cantilever to oscillate it and apply actuation pulses. The system and methods, and adjustments of the geometrical parameters, may be performed to yield a nominal natural frequency in the system. The excitation of actuators with signals corresponding to the natural frequency may induce resonance in the system and may result in high amplitude vibrations and displacement of the cantilever tip of the micro-cantilever. Various architectures of the actuators may be implemented to stimulate different frequencies of the beam and induce displacement in different direction and amplitudes.

    Abstract: The MEMS thermal actuator (10) includes a microelectronic substrate (14) having a first surface (26) and at least one anchor structure (18,20) affixed to the first surface (26). A composite beam (12) extends from the anchor(s) (18,20) and overlies the first surface (26) of the substrate (14). The composite beam (12) is adapted for thermal actuation, such that it will controllably deflect along a predetermined path that extends substantially parallel to the first surface (26) of the microelectronic substrate (14). In one embodiment the composite beam (12) comprises two or more layers (28,30) having materials that have correspondingly different thermal coefficients of expansion. An electrically conductive path may extend throughout the composite beam (12) to effectuate thermal actuation. In one embodiment of the invention a two layer composite beam comprises a first layer (28) of a semiconductor material and a second layer (30) of a metallic material. The semiconductor material may be selectively doped during fabrication so as to create a self-contained heating mechanism within the composite beam. The invention also comprises a MEMS thermal actuator that includes two or more composite beams disposed in an array.
